How about Poliwag learning Mega Punch... What's up with that?
Punching is done with a fist... POLIWAG HAS NO FISTS!!!
What's it gonna punch with, it's ****ing tail!?
Or maybe Torchic being able to learn Seismic Toss - those feather duster wings can't even get it off the ground - how are they gonna huck a Machamp or a Venusaur around?
